Joely Fisher opened up about the heartbreaking last moments at her famous half-sister Carrie Fisher’s hospital bedside, revealing a hunch she had about the late actress’ mother, Debbie Reynolds.

“I knew that if Carrie wasn’t going to survive this that Debbie would not,” she said in an interview with ABC News this week. “She would not last without her on the planet. She wouldn’t, and she didn’t.”

The “Star Wars” heroine died on Dec. 27, 2016, days after suffering a heart attack onboard a flight bound for Los Angeles. Reynolds, a Hollywood icon, died just one day later following a stroke.

“I’ve been having an out-of-body experience,” Joely said about the tragic loss. “The world lost Carrie and Debbie ... and we lost our hero.”

Joely and her younger sister, Tricia, share a father, Eddie, with their well-known older half-sister. The two women told ABC’s Chris Connelly that Carrie was extremely generous and sensitive.

“She was the coolest big sister in the world,” Tricia, 48, said. “She was a badass body gun-toting princess. Who has that?”
